金刚石

In order to improve the diamond tool performance and the bond strength between substrate and plating, and to obtain the machining efficiency and tool life, this article applies the rare earths to the manufacture of electroplated diamond tools. The effect of LaCl_3·7H_2O additive contents on bright nickel electrodeposits was studied in a typical nickel electroplating solution.

The research results showed that resin bond could hold the self-sharpening diamond more tightly than ordinary diamond, for CSD diamonds have irregular shape, rough surfaces and many incurvated angle. Under the condition of the same grinding efficiency, the grinding ratio of resin bond grinding wheels made with self-sharpening diamond was 1.6 times as high as that of the grinding wheels made with ordinary diamond.

试验结果表明，由于CSD形状不规则，有许多凹入角和粗糙表面，树脂结合剂对CSD的把持力较普通金刚石强，所以在磨削各参数相同的条件下，自锐性金刚石砂轮与普通金刚石砂轮相比，其磨削比提高60%以上。

The experiment results show that the lowest synthesis pressure changed with the different proportion of added boron. At the same time, from the color change of synthesized diamond, we can see that it is an effective method to improve the content of boron in diamond crystal.

实验结果表明，随硼添加比例的不同，合成金刚石的最低压力点也不同；同时，通过不同添加比例的硼合成出金刚石的颜色，可得知该方法对提高金刚石内硼含量的有效性。

Due to the action of boron, the diamond has rough grain size, bad crystal shape and complex surface structure.

由于硼元素的存在，Ⅱb型金刚石生长所需的温度和压力条件均高于普通的Ⅰb型金刚石，并且合成出的金刚石单晶粒度较粗，晶形稍差，表面结构比较复杂。

In this paper boron-doped diamond single crystals was synthesized at high pressure and high temperature with iron-based catalyst doped with B4C, h-BN and Na2B4O7. The effects of multiple boron sources on diamond were studied according to the characterization of structure and properties of the boron-doped diamond.
